Identify and treat linking relationships for electronic serials as documented in CCM Module 14.  Provide the appropriate linking fields (and related notes, if necessary) for earlier/later titles, supplements, and other related works.

In general, the links for earlier/later titles should be made to the related electronic version records.  When records for an earlier or later online title do not exist, catalogers are sometimes uncertain as to whether or not to add 780 / 785 linking fields if not also creating a record for the related resource.  The cataloger can leave links out entirely if there is any uncertainty about whether an earlier or later title actually exists.  Alternatively, a linking field containing only the title (or name and title if that is the appropriate entry) can be created without record control numbers to provide a useful bibliographic citation.  Note that the record control numbers, ISSN, and OCLC number were not given in the below example.

A 530 note and field 776 may be used to link a remote access electronic serial to its other physical formats (such as print or CD-ROM).

Alternatively, the 776 field can be used to make the linking note, with an explanation given in subfield $i.

31.16.1.  Multiple linking relationships

Multiple linking relationships also occur with remote access serials.  CONSER's earlier policy of describing multiple relationships in a 580 note and only providing one linking entry field for the primary relationship was made optional in 2006.  Discussion of the practice at the CONSER operations meeting in 2006 led to agreement that providing the multiple linking fields and limiting the use of 580 where possible is more in line with FRBR.  It was also recognized that use of the 580 field will still sometimes be necessary even though the subfield "i" is available for giving link relationship information in the linking fields.  The following example demonstrates uses of note and linking fields to describe a situation where the electronic and print versions were issued simultaneously for some time.  The online version then entirely replaced the print publication.  The overlap of  issues published simultaneously in print and online versions is described in the 580 field of the print version.
